PowerScale OneFS 9.3.0.0 CLI Administration Guide

IPMI overview

OneFS support for the Intelligent Platform Management Interface (IPMI) provides remote access to the OneFS console for performing power management operations remotely on your Generation 6 and PowerScale clusters. Support includes Serial over LAN (SoL).

Using IPMI, you can:
  • Power on nodes or the cluster after shut down, for example, after maintenance or a power outage.
  • Power off nodes or the cluster, for example, after a power outage and when the cluster is operating on backup power.
  • Perform a Hard/Cold Reboot/Power Cycle, for example, if a node is unresponsive to OneFS.
IPMI is disabled by default, and is disabled in releases earlier than OneFS 9.0.0.0. In OneFS 9.0.0.0, use the isi ipmi command to enable and configure IPMI for your cluster:
  • DHCP
  • Static IP address
  • IP address range

IP addresses are assigned on a first-available basis. You cannot assign a specific IP address to a specific node. Use the isi ipmi nodes list command to confirm a node's IP address.

For security purposes, restrict IPMI traffic to a management-only VLAN.

Configure a single username and password for IPMI management for all the nodes in your cluster using isi ipmi user modify --username=<username> --set-password. User names can be up to 16 characters. Passwords must be 17-20 characters. To verify the username configuration, use isi ipmi user view.

The physical serial port is disabled when a SoL session is active. The physical serial port is enabled when the SoL session is terminated with the deactivate command.

You can also access the cluster using the IPMItool in Linux, available as part of most Linux distributions, or accessible through other proprietary tools. See the Linux man page for ipmitool for usage details.

NOTE: Support for IPMI on Isilon Generation 6 hardware requires node firmware package 10.3.2 and SSP firmware 02.81 or later.
